在此之后，它在numberOfRowsInSection崩溃

任何帮助都将不胜感激。提前感谢。

此代码的结果是NSDictionary，但您创建了一个数组对象：


响应指令[@“数据”]；

您可以与服务器讨论，数据必须是一个集合，NSArray的格式，现在它是一个NSDictionary

您有一些错误首先解决它，错误是

您可以在复选框按钮集标记中进行单元设计

[cell.checkBtn setTag:indexPath.row]


管理复选框按钮的检测点击操作
UIButton*按钮=（UIButton*）发送方；
int row=button.tag

使用此行对象管理替换对象
首先，获取所选对象并将其存储在一个NSMutableDictionary对象中
NSMutableDictionary*dic=[detailArr objectAtIndex:row]
B.将对象替换为设定值
[dic设置值：@“1”forKey:@“已检查”]
C.此替换值仅更改“dic”对象，而不是您选择的单元格，因此下面的列表是数组列表中的更改对象
[detailArr replaceObjectAtIndex:row with object:dic]
最后一个是在tableview中

问题是因为“衣服”中的数组是不可变的。我终于找到了解决办法
    detailArr = [[NSMutableArray alloc]init];
    if([responseDict[@"data"] count] > 0){
        keys = [responseDict[@"data"] allKeys];
        NSMutableDictionary *dict1;
        NSMutableArray *arrx;
        for(int i=0;i<[responseDict[@"data"] count];i++){
            arrx=[[NSMutableArray alloc]init];
            arrx = [NSMutableArray arrayWithArray:[responseDict[@"data"] valueForKey:[keys objectAtIndex:i] ]];
            dict1=[[NSMutableDictionary alloc]init];
            [dict1 setObject:arrx forKey:[keys objectAtIndex:i]];
           [detailArr addObject:dict1];
          }

     }
   [_tblVw reloadData];

坠机后日志。

    if([responseDict[@"data"] count] > 0){
        keys = [responseDict[@"data"] allKeys];
